Transcription of footage and source clip markers search

HI there guys.
Just want to ask you for a quick tip. I am developing an app (Edit8 Transcribe) that transcribes interview footage by plugging into Google Speech API. I managed to get the xml parsing right, but I was just wondering how do you actually search the markers? It's been a while since I worked as editor, but I asked myself, why have this marker transcription when you can;t search it? I hope I am not working on an app noone will ever use cause the actual transcription markers can;t be searched ?
I would appreciate if you do now of a way to search them. I tried search bins, but that's not the same.
